I'm not sure of the Code side of an installation like this in US terms, but this has to be one of the roughest ideas I've heard of in a while.
Some "electricians" seem to forget the basic principles of electricity.
Now, what say that there is a decent fault on that circuit and the fault does not clear as it should?.
Anyone ever seen what in-adequately supported wires do under the influence of fault currents?.
I'd sure hate to be standing under that ceiling if a fault did occur, I'd imagine there would be a fair amount of wieght in a bundle like that. [Linked Image]
